Holden vehicles dominated Australian roads for decades before the brand was discontinued in 2020. Millions of Holden Commodores, Captivas, Cruzes, Astras, Colorados, and Trailblazers remain in service, and parts and diagnostic support continue from various GM-related sources. This guide covers the most common Holden dashboard warning lights and what they typically indicate. Check Engine Light […]
P0700 is a transmission control module (TCM) generic fault code that means the TCM has detected a fault in the transmission system but is reporting it through the engine ECM. P0700 itself does not tell you what is wrong – it is a flag that other transmission codes are stored in the TCM. To diagnose […]
Workshop manuals include detailed sections on air conditioning systems: refrigerant type and capacity, component layout, diagnostic procedures, and service specifications. AC repair is one of the more specialised areas of automotive work but the manual’s AC section is essential whether you are diagnosing a weak system, replacing a failed compressor, or just trying to understand […]
Interior plastics on the dashboard, door panels, console, and trim fade, crack, and become sticky or greasy over time, especially on vehicles parked in direct sun. Australian UV is particularly harsh – vehicles parked outside year-round can show severe dashboard cracking within 5 to 7 years. Proper cleaning, conditioning, and protection keeps interior plastics looking […]
A broken tail light or brake light is a traffic ticket waiting to happen and a serious safety issue – vehicles behind cannot tell when you are slowing down. Replacement is one of the simplest electrical jobs you can do, though access varies significantly between vehicles. This guide walks through diagnosis, replacement, and what to […]
Fiat vehicles in Australia include the iconic 500 hatchback, the 500X crossover, the Ducato large van (also rebadged as the Ram ProMaster in some markets and used as the base for many motorhomes), the Doblo small van, and the Professional commercial range. They share platforms and powertrains with other Stellantis brands (Alfa Romeo, Jeep, Peugeot, […]
Workshop manuals include complete engine overhaul sections with the specifications needed to rebuild or refresh an engine. Even if you never plan to pull an engine apart, understanding what these specs mean helps when diagnosing engine wear issues, evaluating a used engine before buying, or deciding whether a worn engine is worth rebuilding versus replacing. […]
Door hinges, lock mechanisms, boot latches, bonnet latches, and various pivots throughout the vehicle all need periodic lubrication. Squeaky doors are the most obvious symptom, but worn latches that fail to secure properly are a serious safety issue – a boot or bonnet that pops open at speed is dangerous. Annual lubrication takes 15 minutes, […]
Codes P0101 through P0104 indicate Mass Airflow (MAF) sensor faults. These codes are common on older vehicles and cause noticeable drivability issues: hesitation, stalling, rough idle, and poor fuel economy. Diagnosis is usually straightforward if you understand how MAF sensors work and the order to test things in. What a MAF Sensor Does The Mass […]
Headlight lenses made of polycarbonate plastic yellow and haze over time from UV exposure. Beyond the cosmetic impact, hazy lenses scatter light and reduce night visibility significantly – studies have shown light output can drop by 50% or more on heavily oxidised lenses. Restoration is inexpensive DIY work that takes under an hour per lens […]
Mini vehicles (R50/R52/R53 first-generation BMW Mini, R55/R56/R57 second-generation, F55/F56/F57 third-generation, and the latest F66 generation) are owned by BMW and share many components and electronics with the broader BMW range. They have their own characteristic issues that owners and home mechanics should know about, particularly around the prone-to-fail PSA-co-developed Prince engines (N12, N14, N18) used […]
The fuel pump relay is a small but critical component that controls power to the in-tank electric fuel pump. When you turn the key to ignition, the ECM (or in older vehicles, the ignition switch directly) energises the relay coil, which closes the relay contacts and sends 12V power to the pump. When it fails, […]
